I know this is a very general question, but here goes. How long does beer last in a keg? The beer was fermented in a fermenting bucket and transferred to the keg. CO2 added and then in the fridge the keg went. It has been in the fridge at roughly 30 degrees (give or take a degree or two). This having been my first try, I am more curious as to how long. The beer still tastes good, and if anything it tastes a bit better now than when I first did it about a month ago. Any input is greatly appreciated.
